In the drawings is illustrated two forms of this invention.

In the first form as shown in the drawings in FIG. 1, FIG. 2, FIG. 3, FIG. 4 and FIG. 5, the lampshade comprises a plurality of frames 1, each frame having an opening 2 to be covered with a shade material passing light therethrough and a shade holder 3 surrounding said opening on one side of the frame to hold such material. Said shade holder 3 which is a substantially square shaped frame or rigid transparent plastic plate and the frame 1 are attached to each other with a plurality of side hinges 4 and 4A. It is understood that said hinges may be substituted with integral hinges. Each frame 1 having an attaching strip 5 at one end and each shade holder 3 having a preferably threaded central pin 6 and vertical and horizontal supporting slots 7 at the other end. Each attaching strip 5 is having a central opening 8 and provided around said opening with a holding ring 9. In order to connect the separate frames 1 with each other in a square relationship, the central pin 6 at one end of the shade holder 3 is positioned into the central opening 8 of the attaching strip 5 at the other end of the adjacent frame 1, whereby the vertical and horizontal edges of said attaching strip slip into the vertical and horizontal ends of the supporting slots 7. The horizontal ends of said supporting slots 7 at one end of the shade holder 3 serve a dual purpose, to provide the attaching strips 5 with a horizontal support and secure simultaneously the other end of the shade holder 3 of the adjacent frame with the shade material against the same end of the frame 1 when said frames are connected with each other.

The attaching strip 5 serves also a dual purpose, attaching the single frames to each other and as an inside light screen prevents the escape of light at the joint of the attached frames.

In order to secure the connected frames 1 to each other, a screw threaded pin cap 10 is being screwed over the central pin 6 and the brim 11 of said pin cap by penetrating into the holding ring 9 of the attaching strip 5, secures the connected frames 1 together.

Each frame 1 is provided longitudinally at one end thereof with an outside lightscreen 17 which lightscreen is a slight angular extension of one end of said frames and each frame is provided longitudinally atthe other end with an outside lightscreen slot 17A. By connecting two adjacent frames 1 with each other, said outside lightscreen 17 at one end of the frame slips into the outside lightscreen slot 17A on the other end of the adjacent frame 1 in a position corresponding with the square shape of the lampshade, thereby preventing the escape of light from the interior of the lampshade at the joint of said frames 1.

To insert the shade material into the inside part of the frames 1 and the shade holders 3, said shade holders should be opened.

Each frame 1 is provided on its upper end with a horizontal covering strip 18 to cover the upper end of the inserted shade material and on its bottom end with a horizontal holding strip 19 to hold said shade material in position.

To open and close the shade holder 3 easily, the vertical central part of each shade holder having at one end thereof a vertical cut out portion 16 corresponding with the height of the holding ring 9.

The assembled lampshade is attached to the lampbase with a single brace which can be made up either in one piece or in three parts.

Each shade holder 3 is provided at one end thereof with a brace socket 20 and the shape of said sockets always corresponds with the shape of the end portions of said brace. Each of said brace sockets having at one end a brace holding means 21 for securing the brace to the opposite facing two brace sockets 20. Said brace holding means may be a rib or other similar holding means. To provide the inserted brace in said brace sockets 20 with additional support, each of said brace sockets having two vertical supporting ears 15.

To release the secured frames 1, the pin cap 10 should be unscrewed from the central pin 6.

In the other form of the lampshade construction as illustrated in FIG. 6, FIG. 7 and FIG. '8, the central pin 3 6 at one end of the shade holder 3 is substituted with an attaching ear 12. Said attaching ear is provided with sufiicient flexibility either by the natural flexibility of the material used for the lampshade, or in case of rigid materials by appropriate springs.

The supporting slot 7 at the same end of said shade holder 3 is also substituted with the upper and lower supporting slots 7A.

The attaching strip at the other end of the frame 1 is substituted with a sectional upper and lower attaching strip 5A and with a central attaching strip 513. The horizontal ends of said upper and lower supporting slots 7A at one end of the shade holder 3 serve a dual purpose, to give a horizontal support to the horizontal end of the upper and lower attaching strips 5A and to secure vsimultaneously the other end of the shade holder 3 of the adjacent frame 1 with the shade material against the same end of said adjacent frame when said frames are connected with each other.

' Each attaching car 12 is provided at one end thereof with a holding means 13 preferably in the form of a groove or opening and each central attaching strip 5B is provided at one end thereof with a holding means 14 preferably in the form of a rib or other similar holding means.

Each shade holder 3 having at one end an upper and lower inside light screen 17B and at the other end an preventing thereby the escape of light at the joint of said shade holders 3 and providing said connected shade holders with additional firm support.

In order to connect the adjacent frames 1 with each other in this construction, the central attaching strip SE at one end of the frame 1 is being inserted into the attach-ing ear 12 at the other end of the shade holder 3 of the adjacent frame whereby the upper and lower attaching strips 5A penetrate into the upper and lower supporting slots 7A. The rib of the holding means 14 of the central attaching strip 53 by lifting slightly the flexible attaching ear 12 snaps into the groove of the holding means 13 of said attaching ear 12 and secures the two adjacent frames together. To release the secured frames 1 the attaching car 12 should be slightly lifted.

To open and close the shade holder 3 easily, the vertical central part of each shade holder having at one end thereof a vertical cut out portion 16A corresponding with the height of the rib of the holding means 14 of the central attaching strip 5B.

All the other parts of this construction are entirely identical with the parts of the first construction.

In each of said two constructions the four frames 1 are exactly alike. The attaching strips 5, 5A and SB respectively and the central pin 6 and attaching car 12 respectively are so formed that said frames 1 may be connected end to end in interchangeable relation.

The assembled lampshade in both constructions is attached to the la-mpbase with a single brace which can be made up either in one piece as FIG. 9, FIG. 11 and FIG. 12 show it, or in three parts as illustrated in FIG. 10.

It is clearly understood that according to the strength of the materials used for said braces, all the illustrated braces may be narrower or wider in shape and they may be fiat, rectangular or round including the shape of a .single wire and the parts of said braces may be used also in combination with each other within the scope of the invention.

7 It is also understood that said braces can be used not only as a unit with the present invention but also in connection with other lampshades as separate components.

FIG. 9 shows three non-collapsible braces, each made up in one piece. Each of said braces having a base plate 22 with a central hole 23 for attaching said braces through said hole to the lampbase. Both ends of the base plate 22 forming an arm 24 and the degree of angle of said arms regulates the height of the lampshade on the lampbase.
